[REO]

Question. Do you guys have a rule of thumb you would like to share regarding how you decide how much money you are willing to put at risk in a particular stock? Do you base your decision upon volume, float, share price, percentage of your portfolio or how liquid you are at the point of entry? (some, all, none of the above) I read the posts credited to Hack, Lance and Harbs on this board. I've also read some very good info that was provided by Buzz, Omni and a few other respected traders on Ihub, but most of these adress protecting profits once you have entered and not the amount you should enter with.

I'm at the point now where I can risk several K at a time and would appreciate your opinions on this subject.

Thanks in advance.
